Step-by-step explanation:
we can see from the diagram,
AB is line of reflection and P' is the image of point P
now if C is the point of intersection of lines AB and PP'
then we have
PC=P'C
also AB is perpendicular to PP'
hence we have m∠ACP=90°
so we have
A reflection is a transformation that maps point P in a figure, over a line, AB, such that for point C at the intersection of AB and PP', PC=P'C and m∠ACP=90°
If you plug in an x-value into the different equations and check to see if the corresponding y-value is correct, then you can find the correct answer.
For y = x/72, you can check this by plugging in the x-value of 18.
18 / 72 = 0.25
When x was 18, y was 4, not 0.25.
So this is not the correct answer.
y = x / 18
y = 18 / 18
y = 1
When x was 18, y was 4, not 1.
So this is not the correct answer.
y = 18 / x
y = 18 / 18
y = 1
When x was 18, y was 4, not 1.
So this is not the correct answer.
y = 72 / x
y = 72 / 18
y = 4
When x was 18, y was 4.
So this is possibly the correct answer.
Let's test 2 other values to be sure.
y = 72 / x
y = 72 / 36
y = 2
When x was 36, y was 2.
This works.
y = 72 / x
y = 72 / 6
y = 12
When x was 6, y was 12.
This also works.
So this means y = 72 / x is the correct answer.
